My test motherboard may be old, but it's the single most solid overclocking board for the AMD platform I have ever used. Using the KT333 chipset, the EPoX 8K5A+ will do 210MHz FSB without blinking. The default clock speed of an XP1800+ is 1533 MHz, at 266Mhz FSB with a multiplier of 11.5x. The default clock speed of a 2600+ is 2133MHz, some 600MHz higher, with a multiplier of 15x. The 333Mhz version of the 2600+ operates some 50MHz slower, at 2083MHz, with a multiplier of 12.5x. Right away we should be able to increase the FSB to 166MHz, with no additional voltage and be well under spec. Let's find out:
As you can see, no problem at all here. Let's take it up to the 2133Mhz speed. I could do this by changing the multiplier, but a much easier method, and something that will yield better performance, is to just to whack in some good memory and crank up the FSB.
At 2133Mhz, again at stock voltage there are absolutely no issues, with the machine being stable for countless Sandra burn-ins and prime 95 iterations. Time to stop mincing around, let's see how far we can push this puppy.
